UNITED STATES WILLIAM w. WALLACE, or CHICAGO, ILLINOIS; LIL AB. wismcmnmmmmmx Q 1 or SAID wrLnrAmw. wAL AcnpncEAsEn Application filed August 25,1930. Serial No. 477,630.

This invention 7 relates to a brick setter and more particularly tothe mechanism for operating the brick clamps on the fingers and elevating the same.

- The invention comprises the novel struc- In the accompanying drawings which illustrate a preferred form of this invention and in which similar reference numerals refer to similar features in the different views; Figure 1 is a front elevationalaview of a brick setter involving this invention; Figure 2 is a sectional view upon the line IIII of Figure 1; and i Figure 3 is a side elevational view of the brick setter.

Referring to the drawings, there is shown 20 frame comprising the finger beam 1 from which the fingers 2 extend that carry the brick clamps (not shown) as is well known in the art. The brickclamps are'operated by rods 3 (Figure 3) which are pivoted to 25 crank collars 4 rotatably mounted upon rods 5 and actuated by spring controlled rods 6 which-extend through a lifting bar 7 which V is attached to yokes 8. Only a fewof the I rods 6 are shown. This mechanism has not i 39 been fully illustrated asit isold and'well known in the art and forms no part of this 1 invintion, exceptas it'may cooperate therewit 2 The invention concerns itself more direct- Y 1y with the means for elevating the lifting bar 7 for applying the clamps and for elevating the load. To thisend, the yokes 8 are pivotally connected to 5 intermediate parts of levers 9 which are-pivoted at their 40 outer ends to pivots 9*;carried by brackets 10 se'curedto the diagonal struts 11 of the The inner ends of the levers 9 are pivotallyconnectedto short frame of the machine.

. links 12 which in turn' are pivotally ati 45 tached intermediate the ends of a lifting .bar 13 which extends through slots in guide members 14 extendingqfrom the vertical posts 15 of the frame-work.

- Theends of the lifting bar 13 are pivotal- 50 ly attached to hollow link members 16 by means of the pivot 16*. ure 2) slidably extends into each hollow link member and is adapted to be connected V thereto by a connecting pin 18 (Figure2),

These connecting pins 18 are pivoted in the.

bifurcations of arms 19 which are firmly secured upon an operating shaft 20 journaled in bearings 21 upon the members 16, and in bearings 22 upon the transverse, angle frame member 23 which is connected to-brackets 23' extending from the diagonal struts 11. This. shaft 20 is provided with an operating handle 24.,whereby the 7. same may be ro v tated .to simultaneously withdraw the pins 18 and disconnect the rods 17 from the link members '16, a feature which maybedesirable in some instances; for example, when 1 a load of brick is deposited upon a wagon;

0r platform, the disconnection of, the pins P 18 will remove all tendency to again grip the bricks when the apparatusis removed and returned'to the pile for another-load. j w The upper ends of the rods 17 embody 'ad-' justable screws 25 whichare connected with 1 clevises'26 suspended from the forward ends. of levers 27.. The rearv ends of; the levers A nod-17' 27 are "pivoted to, rearwardly extending arms 28 on the posts 15, and intermediate of 1 their ends they are pivoted to levers 29,

(Figure The forwardends of the levers connected to .a turntable 32. The forward portions of the levers 27 are also connected by links 33-with said turn table.

' 8o 29 are/pivoted tolugs 30 on t e-posts oruP- The aforementioned levers 9"are' normallyforced downwardly to'releasethe brick I Q clamps by means of coil springs34. To this end a saddle member straddles each lever -9. A guide pipe 36 extends upwardly from g each saddle 35 for guiding the spring 34.

An adjustable rod 37, slidingly fits in each guide pipe 36. Theupper ends of the rods 37 are adjustably connected to bracket 23? by means of the nuts 38.

The brackets 10 and 23 areconnected by. brace rods 39 as shown in' Figure 3 to strengthen and giveqpropersu'pport to the same. The uprights 15 are also braced by far interior struts 40. The frame of the machine may, however, be constructed in any suitable manner.

It will be noted that the system of levers 27 and 29 will lift the load in balanced and even position Without any tilting thereof, and that the lifting mechanism may-be'disconnected from the clamp applying mechanisln .at any desirabletime. I m I am aware that many changes may be made and numerous details of constructlon may be varied through a Wide range without departing from the principles of this invention, and I, therefore, .do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.

'I'claim as my invention:

-1. In abricksetter, a finger frame includinga pair of uprights having parallel arms,

wbrick-clamp operating mechanism, .a pair of levers connected to said mechanism and to said arms, a second pair of levers connected to said uprights andv pivoted intermediate their ends to said first pair of levers,

2a turn table and links connecting said levers and turntable.

2. In a brick handling machine, a, frame, lifting levers pivoted to said'frame, lifting fingersca'rried by said frame, brick clamps ggwoperating mechanism, a'pair of links depending from saidlevers', a pair of links extending upwardlyfrom said brick clamps operating mechanism, a transversely extending shaft carried by said last mentioned klinks,crank arms secured to said shaft, and locking pins carried by said crank arms for locking the pairs of links together.

'3. In a brick handling machine, a frame including lifting fingers, brick clamps op 0 erating mechanism, levers connected to said frame, a pair of depending links on said levers, a pairof upstanding links on said mechanism, said depending and upstanding li'nks having apertures adapted to be :"brought into registry,atransverse shaft carried by one pair of links, crank arms on said shaft, pins carried by said crank arms for engaging in said apertures and'means for rotating said shaft.
